The tweet included two images of a letter from the law offices of Wildes and Weinberg which stated that the former model immigrated to the United States legally.

"Mrs. Trump became eligible for citizenship in 2006, after five years of continuous permanent residence," wrote Michael J. Wildes, an immigration attorney, who also works with the Trump Foundation.

The statement comes in the wake of a row over allegations that the Republican nominee's wife possibly worked as a model in the United States in 1995 while on a visitor's visa.

According to CNN, the New York Post re-published photos of a photoshoot she had done in the 90s, which seemed to place her in New York City in 1995, despite her claims that she had arrived in 1996, pointing towards immigration discrepancy.

In the model's defense, Wilde's further said, "Following a review of her relevant immigration paperwork, in can unequivocally state that these allegations are not supported by the record, and are therefore completely without merit."

Melania's public appearances have gone down drastically after an embarrassing incident in July in which she was caught plagiarizing First Lady Michelle Obama's speech.

Her speech to the Republican National Convention in Cleveland, Ohio, contained two passages that matched word-for-word the speech that first lady Michelle Obama delivered in 2008 at the Democratic National Convention.

The Trump campaign called the accusation "crazy" followed by a series of contradictory statements.

While Trump congratulated his wife on Twitter for giving the most publicized speech "in the history of politics", the former model's speechwriter, Meredith McIver, said in a statement that she was responsible for including passages from a speech Mrs. Obama delivered.
